Trying to bleed brakes, but getting no fluid out

Bleeding the brakes is a 2 person job. One to open and close the valve at the caliper and another stepping on the brake pedal to force the fluid out.

Emergency Brakes feel like they are set but are not

I have the same problem with my 06 G6. The pins in your calipers are likely seized. Try cleaning or replacing the slide pins. If that doesn't help, it's probably time for calipers.
